"As with all law enforcement involved deadly force events, we are unable to provide further details while the Interagency Deadly Force Investigation Team investigates the incident," the Lane County Sheriff's Office said. "Any future information will come from the District Attorney’s Office at the conclusion of the investigation."

Deadly Force Investigations

Investigations into the use of deadly force by law enforcement in Oregon are governed under Senate Bill 111, passed by the 2007 Oregon Legislature.

Lane County adopted guidelines under the law in 2008.

After a law enforcement officer uses deadly force, the county's Interagency Deadly Force Investigation Team must follow the state-approved protocols.
